|J-2X: From Concept to Hot Fire|
The author/director of this creative piece is Paul Gradl who works on the J-2X development effort. A superb engineer with a technical background in combustion devices design and analysis, he came up with the notion of stringing together the J-2X development process starting with conceptual design, then detailed design and analysis, through fabrication and assembly, and finally into full-scale hot-fire testing...

|J-2X Rocket Engine, 40-Second Test|
NASA conducted a 40-second test of the J-2X rocket engine Sept. 28, the most recent in a series of tests of the next-generation engine selected as part of the Space Launch System architecture that will once again carry humans into deep space. It was a test at the 99 percent power level to gain a better understanding of start and shutdown systems as well as modifications that had been made from previous test firing results.

|J-2X Engine Test, May 16, 2012|
The shake, rattle and roar lasted just seven seconds, but the short J-2X test conducted May 16 at NASA's John C. Stennis Space Center moved the space agency closer to a return to deep space. NASA operators tested the next-generation J-2X engine on the A-2 Test Stand at Stennis to collect early data on performance of the engine and test stand with the new nozzle extension and clamshell configuration...

|J-2X Engine Continues to Set Standards|
Testing of the next-generation J-2X rocket engine continues to set standards. Last fall, the engine attained 100 percent power in just its fourth test and became the fastest U.S. rocket engine to achieve a full-flight duration test, hitting that 500-second mark in its eighth test. On, May 25, NASA recorded another first during a 40-second test of the engine on the A-2 Test Stand at John C. Stennis Space Center...

|Throttle Up! J-2X Powerpack Test Sets Record|
During a record-breaking June 8 test, engineers throttled the J-2X powerpack up and down several times to explore numerous operating points required for the fuel and oxidizer turbopumps. The results of this test will be useful for determining performance and hardware life for the J-2X engine turbopumps. The J-2X engine will power the upper stage of the evolved NASA¹s Space Launch System, an advanced heavy-lift rocket that will provide an entirely new national capability for human exploration be...

|Small Solid Rocket Motor Test|
It was three-two-one to brilliant fire as NASA's Marshall Space Flight Center tested a small solid rocket motor designed to mimic NASA's Space Launch System booster. The Mar. 14 test provides a quick, affordable and effective way to evaluate a new nozzle insulation material for the SLS solid rocket booster. (NASA/MSFC)
